Please explain I don't understand! 1. Write the equation of the parabola in standard form (standard form is (x – h)2 = 4p(y – k) ). Use the center of the roadway as the origin (0,0).

2. Identify the vertex, directrix, focus, latus rectum, domain, and range of the parabola. Restrict the domain and range to the values applicable for this particular bridge, not the equation of the parabola itself (neither domain nor range should have infinity or negative infinity in the answer)

3. Determine the number and length of each of the vertical cables needed between the two towers. Include the total feet of all the vertical cables added together. Enter your data in the table below. Round each length to the nearest tenth of a foot. Some data has been entered for you already.
